Spin-Exchange in Hydrogen-Antihydrogen Collisions
We consider the spin-exchange in ultracold collisions of hydrogen (H) and antihydrogen (H̄) atoms. The cross sections for transitions between various hyperfine states are calculated. We show that the process of spin exchange in H̄ − H collisions is basically driven by the strong force between proton and antiproton, that spin-exchange cross-sections are proportional to the difference of singlet an...
متن کاملSimulations of antihydrogen formation
The results of simulations of antihydrogen formation in a Penning trap are reported. The antihydrogen atoms are formed by three-body capture. We find that the arrested nature of the three-body capture in the trap greatly reduces the expected binding energy of the antihydrogen. Typically, the formed antihydrogen has larger velocity along the magnetic field than across the field and a binding ene...
متن کاملLow-temperature antihydrogen-atom scattering
A simple method to include the strong force in atom–antiatom scattering is presented. It is based on the strong-force scattering length between the nucleon and antinucleon. Using this method elastic and annihilation cross sections are calculated for hydrogen–antihydrogen and helium–antihydrogen scattering. The results are compared to first-order perturbation theory using a pseudo potential. The...
متن کاملSpatial distribution of cold antihydrogen formation.
Antihydrogen is formed when antiprotons are mixed with cold positrons in a nested Penning trap. We present experimental evidence, obtained using our antihydrogen annihilation detector, that the spatial distribution of the emerging antihydrogen atoms is independent of the positron temperature and axially enhanced. This indicates that antihydrogen is formed before the antiprotons are in thermal e...
متن کاملA portable positron accumulator for antihydrogen formation
A pulsed source of positrons has been developed which may be useful for antihydrogen (Iq) formation because it is portable when compared to accelerator-based sources. This positron accumulator uses a Penning-style trap to collect moderated positrons from a radioactive source. The positron pulses may be emitted with repetition rates in the range of 50-1000 Hz, which is appropriate for I:I produc...
